Anybody willing to pay the asking rent of £90,000 a year can take over the 13-hectare site in a secluded forest in eastern Poland, which during the war lay in German East Prussia.

From 1941 to the end of 1944 the Wolf’s Lair was the nerve centre of the Nazi war machine owing to its proximity to the Eastern Front.

The Polish Forestry Service, the owners of the camp, started looking for a tenant after the old 20-year lease expired.
